"The Criterion, or Cri: a marvel of a theatre, built entirely underground"

 The Criterion Theatre at Piccadilly Circus opened in 1874.

As noted in the text, the theatre was almost entirely underground, there being a restaurant on the ground floor of the building, and a ballroom on its first floor.

Both the theatre and the restaurant are still in existence, although the building in which they are housed underwent substantial modifications during the late 1980s and early 1990s.
